Prime Minister John Key has done an about-face after denying he had a discussion with MediaWorks bosses before the Government decided to give the company a $43.3 million helping hand.

He has now admitted meeting then-MediaWorks boss Brent Impey two months before, when Mr Impey pressed his case for a scheme the Government initially turned down.

The scheme, announced in October 2009, allowed radio companies to spread payments on 20-year broadcasting licences over five years, instead of one lump-sum payment.

On Monday, in answer to written parliamentary questions, Mr Key said he had not had any discussions with MediaWorks, which owns TV3 and a network of radio stations.

But on Wednesday, he issued a correction, saying he "ran into Brent Impey at a social event [in August] where he briefly raised the issue".

Labour MP Trevor Mallard, who lodged the questions, said the meeting must have made an impact because the Government ended up approving a scheme it had earlier rejected, even though the essential elements remained the same.

"I can't work out whether Mr Key is accidentally slipping and genuinely forgot he had the meeting, or whether he is being deliberately misleading," Mr Mallard said.

Mr Key said the Government had been considering the proposal long before Mr Impey's lobbying.

"He just raised it as an issue, but we had been looking at that for some time."

Documents released to One News under the Official Information Act show that the Government declined a request for help in May 2009.

Communications and Information Technology Minister Steven Joyce, who once owned RadioWorks but sold it in 2001, wrote to the Radio Broadcasters' Association rejecting a deferred-payment plan on advice from the Ministry of Economic Development. The ministry said it would place the Government in a credit financing role, which the market already provided, and noted that radio networks had known about the payment for some years.

MediaWorks continued to lobby ministers and told the Government it needed an answer by the end of October, when it had to make long-term financial restructuring decisions.

Mr Joyce presented a paper to the Cabinet on October 12 which included Treasury advice opposing the scheme, partly because other licence users, such as TV companies, might ask for the same treatment.

October 2009: Draft Cabinet paper notes Treasury opposes the
scheme as it overturns long-standing policy and may see others, such as
TV companies, ask for similar treatment. Also notes a lump sum
payment would not threaten the long term viability of MediaWorks
or The Radio Network, but it would impact profitability.

October 2: Joyce writes to Key seeking to present a paper to Cabinet on Oct 12, proposing deferred payments scheme.
